Question

Identify m∠U and m∠X.

Answer 1

Since
angle U= angle X

4x=x+42
4x-x=42
3x=42
x=14


m angle U=4x=>4×14=>56°
m angle X=x+42=>14+42=>56°

Answer 2

since the Similarly crietria


<U = <X

so ,

4x = x + 42

3x = 42

=> x = 14


and < U = 4x = 14× 4 => 56


and < x = 14+ 42 = 56


hence option number a is correct
